Subreddit discovery tools, tested live
Redditlist.com still loads, but it stopped moving years ago. Its SSL certificate expired on 7 March 2025, its homepage has not changed since 2 March 2023, and it still lists r/funny at about 25 million subscribers while Visual Capitalist counted roughly 67 million in May 2025. The best free replacements split its job: a matching tool to find subreddits for your product, an analyzer for activity and posting times, Reddit Pro for official keyword trends, and F5Bot for alerts.
We opened every tool on this page on the same day, and some popular picks from older lists did not survive: GummySearch closed in November 2025, and the Frontpagemetrics domain now serves an unrelated gambling page. Below is what still works, what each one costs, and an honest note on where each falls short, including our own two free tools.
Is redditlist down?
Redditlist describes itself as tracking the top 5000 subreddits, ranked by activity, subscribers and 24-hour growth. Here is what we found when we loaded it.
SSL certificate

r/funny on Redditlist
25,058,374
Visual Capitalist reported about 67 million members in May 2025.
r/AskReddit on Redditlist
23,296,387
Visual Capitalist reported about 55 million members in May 2025.
The features themselves are simple and still visible: ranked tables for all, SFW and NSFW subreddits, category pages from Art to Technology, a tag voting panel, and a flair browser. There is no signup, no pricing page and no paid plan, and there never were alerts, keyword tracking or any way to tell it about your product.
The problem is the numbers. A ranking that still shows r/AskReddit at about 23 million subscribers, when Visual Capitalist put it near 55 million in May 2025, will send you to the wrong communities with confidence. If you only want a nostalgic look at how Reddit used to rank, it is harmless. If you are choosing where to spend a month of posting, it is the wrong tool.
What happened
Most directory and analytics sites ran on cheap access to Reddit's data. That access changed in 2023, and the effects are still rolling through.
Reddit starts charging for its API. The popular Apollo app announces it will shut down on 30 June 2023, saying the new pricing would cost it about $20 million a year, per TechCrunch.
Free data sites slow down or freeze. Subredditstats now shows a banner saying its data is likely out of date, and that the new API pricing would cost it a couple thousand dollars a month.
Reddit launches Reddit Pro, a free set of tools for businesses, in beta, per TechCrunch. Official data starts to replace scraped data.
Reddit adds Pro Trends for keyword and conversation tracking across communities, per PPC Land.
GummySearch closes for business, citing Reddit API policies that forbid commercial applications, per its closing note.
The takeaway for picking a replacement: prefer tools that either use Reddit's own data (Reddit Pro), do something that does not depend on a live firehose (matching a product to communities, alerts on new posts), or clearly say how fresh their numbers are. Anything that promises a complete, up-to-the-minute ranking of every subreddit deserves a quick spot check against the subreddit itself.
Before you bookmark
Many Redditlist alternative lists still recommend these. We checked each one on 22 September 2026.
| Tool | Status | What we found | Source |
|---|---|---|---|
| Redditlist.com | Online but frozen | Loads behind an expired certificate, with subscriber numbers from years ago. Fine for nostalgia, not for decisions. | redditlist.com |
| GummySearch | Closed 30 Nov 2025 | Shut down to comply with Reddit's API policies on commercial apps. It says over 140,000 founders, marketers and investors used it. | GummySearch closing note |
| Frontpagemetrics | Domain repurposed | On 22 September 2026 the domain served an unrelated Korean-language gambling review page. We do not link to it. | Checked directly |
| SocialGrep | Unreachable at check | Both socialgrep.com and www.socialgrep.com returned Cloudflare error 523 (origin unreachable) when we checked. | Checked directly |
| Subredditstats | Online, self-flagged stale | Still serves charts, but its own banner says the data is likely out of date since Reddit changed its API. | subredditstats.com |
From founders who needed the right subreddits
Three founders who posted on X about using MediaFast to find where to post on Reddit.
"Reddit has insane potential for founders. But most posts get removed. Most accounts get banned. Most strategies are guesswork. I've been using @mediafa_st to plan posts, find the right communities, and avoid bans."
"Should be $25k + $94 now. Just bought lifetime access"
"Things are going well mate thanks for you product. It helps me to step into reddit very intuitively!"
After you find the subreddits
A list of subs is step one. MediaFast turns it into a daily plan: which sub, which post, which thread to comment in, all checked against each community's rules.
Not sure which one fits? Compare every plan side by side further down this page.
The shortlist
Ranked by how well each one replaces a part of Redditlist's job. Every card has an honest limit, including ours.
What it does
Describe your product in a sentence and the tool returns 12 matched subreddits, each with an estimated member count, how tolerant the community is of self-promotion, a suggested posting window and a one-line reason it fits.
Honest limit
The sizes and posting times are AI estimates, so open each subreddit and confirm the rules and member count before you post.
What it does
Pick subreddits and see subscriber counts, a 7-day activity view, an hourly heatmap and the windows when most users are online, side by side.
Honest limit
It covers the subreddits MediaFast tracks, not every community on Reddit, so niche subs may not be in the list yet.
What it does
Reddit's own business toolkit launched in beta on 8 March 2024. Pro Trends, added on 7 January 2025, tracks keywords and shows which communities discuss them and how often.
Honest limit
Built for brand accounts and keyword tracking, not for browsing a ranked list of subreddits the way Redditlist did.
What it does
Emails you when a keyword shows up in a new post or comment on Reddit, Hacker News or Lobsters. Running since 2017, it says it delivers 430,000+ alerts a day.
Honest limit
No discovery or subreddit stats at all. The free tier is personal use only and alerts can take up to 2 hours.
What it does
Subscriber history charts and ranking lists per subreddit, plus overlap tools that show which communities share users.
Honest limit
Its own banner says the numbers are likely out of date since Reddit's API change, so use it for history, not for today's size.
What it does
An interactive map where each dot is a subreddit and clusters form around communities whose users comment in both. Built from 176,178,986 comments left in 2020 and 2021.
Honest limit
The data is a 2020 to 2021 snapshot, so new subreddits are missing. Great for ideas, weak for current numbers.
What it does
Search Reddit for your topic and filter to communities, or run site:reddit.com/r/ plus your keyword in Google to surface threads and the subs they live in.
Honest limit
No ranking, no growth data, and results lean toward the biggest communities, so smaller buyer-dense subs are easy to miss.
What it does
A community-maintained index that groups subreddits by category, the closest thing left to Redditlist's category pages.
Honest limit
Curated by volunteers, so it has no live stats and some links will be stale. Pair it with a stats tool.
Side by side
Five jobs people used Redditlist for, and which tool covers each one today.
| Tool | Discover subs | Current numbers | Activity or timing | Alerts | Product fit | Price |
|---|---|---|---|---|---|---|
| Redditlist.com | No | No | No | No | No | Free (frozen) |
| MediaFast Find My Subreddits | Yes | Estimates | No | No | Yes | Free |
| MediaFast Subreddits Analyzer | No | Yes | Yes | No | No | Free |
| Reddit Pro Trends | Yes | Yes | Keyword volume | No | No | Free |
| F5Bot | No | Yes | No | Yes | No | Free / $9.99+ |
| Subredditstats | Yes | No | No | No | No | Free |
| Map of Reddit | Yes | No | No | No | No | Free |
| Reddit + Google search | Yes | Yes | No | No | No | Free |
No single row is all green, which is the honest answer to "what replaced Redditlist": a small stack. For most founders, two free tools cover it, one to find the communities and one to time the posts.
60-second decision
Start from what you used Redditlist for, not from the tool list.
I need subreddits where my buyers hang out
Matches your product description to 12 communities with a self-promotion tolerance note for each.
I have a shortlist and need to know when to post
Shows the hourly heatmap and the windows when most users are online.
I want to know where my category is discussed
Official keyword tracking with the communities that mention it, free for businesses.
I want a ping when my brand or a competitor comes up
Free for 5 keywords, with faster alerts on paid tiers.
I want to explore neighbors of a sub I already like
Shows which communities share commenters, so you find related subs you would never search for.
I only want to browse categories like Redditlist did
A volunteer category index. Check current member counts on each sub before you commit.
Grade any tool
Redditlist looked authoritative for years after it stopped updating. These checks catch that in a minute.
Open a subreddit the tool lists and compare its member count with what Reddit shows today. A big gap means frozen data.
Good tools say when data was collected. No date plus round numbers is a warning sign.
Members include dormant accounts. Look for posts per day, comments per post or an hourly activity view.
A small subreddit full of your buyers outperforms a giant general one. Prefer tools that start from your product.
A subreddit that bans promotion is useless for launch posts no matter its size. Check the sidebar before anything else.
Do it in one sitting
A step-by-step order that ends with a shortlist you can post to this week.
Finding new subs, sizing up competitors' communities, or spotting growth. Each job maps to a different tool in the table above.
Describe your product in Find My Subreddits and copy the 12 matches into a note. It takes about a minute.
Open every sub, read the rules and pinned posts, and scroll the last week. Cut any that ban promotion or look dead.
Run the remaining 3 to 5 through the Subreddits Analyzer and note the busiest windows.
Add your brand and one or two competitors to F5Bot. The free tier covers 5 keywords.
Communities change moderators, rules and energy. A 15-minute review every few months keeps your list honest, which a static directory never did.
If you would rather not run this every time, MediaFast keeps the shortlist, rules and post drafts for each community in one place, so the research step does not start from zero on the next launch.

"How To Find Subreddits On Reddit Tutorial" by Easy Solution, uploaded 8 March 2024.
Avoid these
Most of the pain comes from treating a new tool like the old directory.
Trust a subscriber number without checking the subreddit itself.
Bookmark an old list that still recommends GummySearch or Frontpagemetrics.
Pick subreddits by size alone. Dormant members inflate every count.
Spot check one number per tool against Reddit before you rely on it.
Start from your product and audience, then look at size and activity.
Read the rules and last week of posts before your first promotional post.
Quick reference
Members
What Reddit now shows instead of subscribers. Everyone who joined, active or not.
Activity
How much posting, commenting and browsing happens in a period. The number that predicts whether a post gets seen.
Growth
Change in members over a window, like the 24-hour growth Redditlist ranked by. Only useful when the data is fresh.
Self-promotion tolerance
How much a community allows posts about your own product, from banned to welcome in a weekly thread.
Keyword alert
An email or webhook when a word shows up in a new post or comment, the job F5Bot does.
Community overlap
How many users two subreddits share, the idea behind Map of Reddit and Subredditstats overlap tools.
Redditlist made subreddit size easy to scan, and for years that was enough. In 2026 it shows numbers from years ago behind an expired certificate, and several tools that replaced it have closed too. The durable setup is small and mostly free: match subreddits to your product, verify them on Reddit, time your posts with activity data, and let alerts tell you when your topic comes up.
Tools like MediaFast wrap the first three steps into one flow, but every tool on this page works on its own. Pick the row in the comparison table that matches your job and start there.

Straight answers on what happened to Redditlist and what to use instead.
It still loads, but it is frozen. When we checked on 22 September 2026, redditlist.com served its homepage with a Last-Modified date of 2 March 2023, and its SSL certificate expired on 7 March 2025, so most browsers show a security warning first. Its subscriber numbers are years out of date: it lists r/funny at 25,058,374 subscribers, while Visual Capitalist reported about 67 million members in May 2025.
Redditlist.com is a free third-party directory that describes itself as tracking the top 5000 subreddits. It ranks them by recent activity, subscribers and 24-hour growth, splits them into SFW and NSFW categories, and lets visitors vote on tags and browse post flair. It never had a paid plan, alerts or any way to match subreddits to a specific product.
It depends on the job. To find subreddits that fit a product, MediaFast's free Find My Subreddits tool returns 12 matched communities from a one-line description. To see activity and best posting times for a subreddit, use the free MediaFast Subreddits Analyzer. For official keyword and community trends, Reddit Pro is free for businesses. For mention alerts, F5Bot's free tier covers 5 keywords.
Sites like Redditlist were built on cheap or free access to Reddit's data. In 2023 Reddit started charging for its API, and third-party apps such as Apollo shut down on 30 June 2023 over the new pricing. Subredditstats now shows its own banner saying its data is likely out of date for the same reason, and GummySearch closed on 30 November 2025 to comply with Reddit's API policies on commercial use.
No. GummySearch closed for business on 30 November 2025. Its founder wrote that the shutdown was to comply with Reddit's API policies, which forbid commercial applications. New signups are closed, free users can only export their data, and lifetime deal holders keep access until 30 November 2026.
We would not use it. When we loaded frontpagemetrics.com on 22 September 2026, the domain served an unrelated Korean-language gambling review page instead of subreddit data, so we removed it from our list and do not link to it.
F5Bot has a free tier for personal use with 5 keywords and alerts within 2 hours. Paid tiers listed on its pricing page are Silver at $9.99 per month (20 keywords, alerts within 5 minutes), Gold at $49.99 per month, Platinum at $214.99 per month, and Diamond from $500 per month. It monitors Reddit, Hacker News and Lobsters.
Yes. Reddit launched Reddit Pro as a free suite of business tools in beta on 8 March 2024, and added Reddit Pro Trends, a keyword and conversation tracker, on 7 January 2025. It is aimed at businesses and gives official data on where and how often a keyword is discussed, which is something Redditlist never offered.
Subscribers (Reddit now shows them as members) is everyone who ever joined, including dormant accounts. Activity is how many people post, comment and browse right now. A community with a huge member count and a quiet feed is worth far less for marketing than a smaller one with daily discussion, which is why a size-only ranking like Redditlist was always a weak signal.
Describe your product and audience, generate a shortlist with a matching tool such as MediaFast's Find My Subreddits, then open each community and read the rules, pinned posts and the last week of posts. Keep the 3 to 5 where your buyers ask real questions and promotion is at least tolerated, then check activity and posting times before your first post.
Partly. Subredditstats still loads historical subscriber charts, but its own banner warns the data is likely out of date since Reddit's API change, so treat recent points with caution. For current size, open the subreddit itself and read the member count Reddit shows today.
A few newer directory sites exist, but many are thin lists with no stated data source. Before trusting one, check that its numbers match what Reddit shows on the subreddit today. For a community-maintained index, r/ListOfSubreddits groups subreddits by category, and Map of Reddit shows which communities share commenters.
Describe your product and MediaFast finds the subreddits where your buyers are active, checks their rules, and drafts a post for each one.
